Unable to connect to a Cisco VPN using SLED 10
This document (3624897) is provided subject to the disclaimer at the end of this document.
Failure to connect to a Cisco VPN when using NetworkManager or vpnc on SUSE Linux Enterprise Desktop 10.
While trying to connect to a Cisco VPN using the terminal application (vpnc) the following error is received:
vpnc: binding to port 500: Address already in use
During the installation of SLED 10 there is an option to install extra software. If the Novell Applications section was selected then it installs a package for connecting to Nortel VPN networks. The package is called turnpike. This package creates a service called racoon which listens on port 500. This causes a conflict since the Cisco VPN is also trying to use port 500.
- A quick and easy test to see if this is your issue is to first
see if you have the racoon service listening on port 500. This can
be done by opening a terminal and typing the following
lsof -i :500
- If you receive a line back similar to the one listed below then
you know that the racoon service is listening on that port.
racoon 4998 root 9u IPv4 24969 UDP localhost:isakmp
- One easy test is to simply kill the process and then see if you
can connect to the vpn.
- A more permanent workaround is to remove the turnpike package.
This can be done by going into Yast, Software, Software Management
and doing a search for turnpike. Once it is found, click on the
check box twice to change it to a trash can. Then click Next and it
will remove the package.
